Patent GB-192995-A (GB)
IPC: B25B5/10
Filed: 1922-05-05
Abstract: 192,995. Waffenfabrik Mauser Akt.- Ges. Feb. 11, 1922, [Convention date]. Screw-and-nut mechanism.-A screw-clamp of the kind provided with a releasable nut to permit of rapid adjustment is so constructed that the nut is looked in its operative position by means of pressure exerted by the screw. As shown applied to a clamp in which the screw e is passed through an unthreaded guide i on a stirrup c of the clamp, a half-nut a is mounted on a spring-pressed bolt b which normally keeps the upper surface of the nut a in contact with the guide i. When the nut a is moved out of engagement with its thread by pressing on the tailpiece h the nut a and bolt b are moved downwards to the position shown in Fig. 2, by the action of a bevelled locking-lug d on a bevelled recess f in the guide i. When the nut a moves back into engagement with the screw the lug d is engaged by the bevelled recess f, and is maintained in this recess by the pressure exerted by the screw e, so that the nut cannot be released unintentionally when the clamp is under pressure. Two half-nuts a may be employed if desired.

Title: Improvements in or relating to the production of deuterium-enriched hydrogen
Inventor: DENTON WILLIAM HAVELOCK
IPC: C01B4/00
Filed: 1957-04-24
Abstract: Deuterium-enriched hydrogen is produced by supplying water of natural D-content to a dual-temperature water-hydrogen isotope exchange process to produce H2 enriched in D above the natural concentration by a factor of about 1.5, distilling the enriched H2, and recycling the D-depleted H2 from the distillation to the dual-temperature exchange through a high temperature D-transfer apparatus where the depleted H2 is equilibrated with water of natural D-content.  The depleted H2 from the distillation passes as shown (Fig. 2) through high temperature transfer plant to the tapered cascade of dual-temperature D-exchange units having water-steam isotope exchange towers 11, 13, hot catalyst beds 14 at 600 DEG C., and cold catalyst beds 12 at 140 DEG C.  Water flows in closed circuits between towers 11, 13, with D-enrichment in towers 11.  Fresh water is fed in at 16 and withdrawn at 14.  The enriched H2 is withdrawn through condenser 18 to the distillation.  The high temperature transfer plant (Fig. 1) consists of a number of catalyst units 1 at 600 DEG C. arranged alternately and in series with water-steam <PICT:0869415/III/1> exchange columns 2 at 136 DEG C. having water fed in and withdrawn at 3, 4.  The catalyst units and exchange columns are preceded by humidifier 5 and succeeded by dehumidifier 6, which may be in heat-exchange relationship at 8, 9.  The whole system may be operated under 10 atms. pressure and the D-enriched H2 may be burned with O2 to produce heavy water.  Specifications 869,412 and 869,413 are referred to.

Title: Improvements in or relating to the drying of bulbs, bottles and the like
IPC: F26B15/08
Filed: 1944-07-11
Abstract: 584,322. Washing bottles, bulbs &c. JESSEL, R. July 11, 1944, No. 13283. [Class 138 (i)] A machine for washing and drying bulbs of cathode-ray tubes, bottles, &c. is constructed so that the bulbs are finally treated with hot water which is drained and then the bulbs are dried by means of a current of air or other gas which is blown into the interior of the bulb. The bulbs 2 are mounted in cages 1 carried by a rotating horizontal shaft 4, and are held to the cages by clips or by a retaining ring 7 while the bulbs are carried through boiling water in a vessel 8 heated by an electric immersion heater 9. A current of air is blown through tubes 3 which project into the bulbs as these leave the vessel 8 so that the bulbs are dried as they drain by removal of steam trapped in them, and it is stated that staining is avoided. In a modification, the bulbs may be carried by cages on an endless band with tubes projecting into the interiors by means of which jets of air may be blown into the interiors of the bulbs after these have been heated by admission of hot water and the water has been allowed to drain away. The bulbs may be cleaned automatically prior to the treatment set out above.

Title: Improvements in or relating to door locks
IPC: E05B63/20
Filed: 1943-08-17
Abstract: 573,165. Door latches. WIRZ, A. Aug. 17, 1943, No. 13346. [A Specification was laid open to inspection under Sect. 91 of the Acts, Feb. 14, 1944.] [Class 44] In a door latch of the kind in which the main bolt is held by a detent in the retracted position, the detent being tripped on closing the door to allow the bolt to shoot, and an auxiliary bolt is provided to retain the door closed until the main bolt has been retracted far enough to ensure the engagement of the retaining indent, the auxiliary bolt being thereafter retracted, the main and auxiliary bolts are connected by a link or lever arranged so that when the door has been opened and the handle released, the follower in its return movement to normal position acts on the link to complete retraction of the auxiliary bolt. As shown, the main bolt 7 is shot by spring 8 and an auxiliary bolt 9 is slidably housed in the main bolt and shot relatively thereto by a spring 10. The main bolt carries a pivoted lever the upper end 15a of which engages a recess in the auxiliary bolt. The follower 3 and handles 5 carried by the spindle 2 are biased to normal position by a spring 4. The follower arm has a projection 6 engaging a lateral projection on the main bolt, which is withdrawn by depression of handle 5, and a projection 14 adapted to engage the lower end 15 of the lever. When the handle is depressed, both bolts are at first retracted without alteration of their relative position shown until bolt 9 clears the keeper and the door can be opened. At this stage the main bolt has been sufficiently retracted to allow a detent to engage so as to retain the bolt retracted. The detent shown comprises a horizontal lever 12 biased by a torsion spring 11 (anticlockwise Fig. 5) at its pivot so that a depending projection 13 snaps in front of a shoulder on the bolt and a terminal projection 18 projects through the back plate of the casing 1 so as to contact with and be pressed in by the fixed door pane when the door is closed, thus tripping the detent to allow the bolts to shoot. In the dooropening position referred to above, the lever has reached a fixed stop 17. If at this stage the handle be released, the main bolt is arrested by the detent, and the anticlockwise movement of the follower arm causes projection 14 to rock the lever clockwise, thus retracting bolt 9 within bolt 7. If, on the other hand, handle 5 be further depressed before release, stop 17 at first rocks the lever clockwise to retract bolt 9, but when the handle is released, the follower action described above occurs to ensure final retraction of bolt 9 within bolt 7. Stop 17, by engaging a shoulder behind projection 6, limits the extent to which the bolts can be shot.

Title: Improvements in or relating to diffusion means for photographic or cinematographic cameras
IPC: G02B13/20
Filed: 1948-05-18
Abstract: 653,914. Photographic and kinematographic cameras. COUTANT, A. C. May 18, 1948, No. 13420. [Class 98 (i)] A diffusion device comprises, located in the field of the camera objective, a transparent element having an irregular non-planar surface, through which light is transmitted to the objective, and a second transparent element adjacent the first element, optically prepared to control the intensity-distribution of light allowed to fall on the first element. The diffuser shown comprises two transparent discs 1, 2, each with a pattern of concentric circular undulations on its surface. The diffusion depends on the axial separation of the elements, which is adjustable, and disappears if the elements are brought into contact so that the undulations fit together. In another form the surfaces of the two elements have straight V- grooves and ridges which also fit when the elements are in contact. The relative movement to change the diffusion may be oxide, or after enough axial movement to disengage the grooves and ridges, rotational. In a further form, one element .has a narrow spiral groove on its surface, with plane areas between the convolutions, and this may be covered by an opaque spiral band on the other element. The diffusion is controlled by relative rotation of the elements to move the spirals out of register. In all the embodiments the diffusion adjustment may be coupled to the objective focusing adjustment.

Title: Improvements in electro magnetic actuating mechanisms for valves and like timed moving parts of internal combustion engines
IPC: F01L9/20
Filed: 1943-08-18
Abstract: 568,216. Valve gear; oil engines. CASTELLINI, A. P., and ROBEY & CO., Ltd. Aug. 18, 1943, No. 13453. [Classes 7 (iii) and 7 (vi)] A single rotary switch driven in accordance with engine speed opens and closes in timed sequence the circuits to groups of solenoids adapted to move armatures secured to valve stems and an armature secured to a fuel injection pump plunger, the valve solenoids effecting sudden movement in one direction and the plunger being actuated by a group of aligned solenoids progressively energized to effect an extended axial movement of the plunger in both directions. Current supplied to a rotor 5' by a generator or battery 12 is collected from conducting strips 10 on the rotor by brushes 16 on a carrier 13 and passed by them through leads 19 ... 19e to the valves and injection pump. The ends of the strips 10 are cut off obliquely to permit adjustment of the timing by moving the brush carrier 13 axially and the brushes themselves may have some angular adjustability. The currents from the leads 19b ... 19e actuate solenoids 32, Fig. 2, each adapted to move axially a double-tapered armature 29 secured to an austenetic extension 28 of the valve stem 27, the whole being enclosed in a non-magnetic cap 34 having in its top a central ventilation aperture. From the leads 19, 19a current energizes a series of superposed solenoids 32, Fig. 4, which attract spaced armatures 29 on an extension 39 of the plunger 41 of a fuel injection pump. As shown, the spacing between the armatures increases progressively to give a longer stroke to the piston which is moved upwards by the top three solenoids when energized from the lead 19a and downwards by the lower two solenoids when energized from the lead 19.

Filed: 1956-05-02
Abstract: A method of manufacturing a permselective membrane comprises the formation of a film of a polymer which is subjected to the action of high voltage electrons, X-rays, gamma rays or similar high energy ionizing radiation, to cause cross-linking of the material of the film to form a film which is insoluble in water or aqueous solutions of electrolytes, the film either being formed from a monomer or polymer of a substituted olefin of which one of the substituents is an acid or basic ionic group or being formed from a non-ionic monomer or polymer which is polymerized and/or cross-linked by the ionizing radiation to form a non-ionic cross-linked polymer, into which acid or basic groups are introduced by chemical reaction after the crosslinking.  Starting materials containing ionic groups include acrylic, methacrylic, itaconic, crotonic, maleic and fumaric acid, vinyl sulphonic acid, ortho or para vinyl benzoic or vinyl benzene sulphonic acid, 2- or 4-vinyl pyridine, ortho or para vinyl benzylamine, dialkylaminoethyl acrylates and methacrylates and polymers p  thereof.  Non-ionic monomers include styrene, vinyl toluene, alpha-methyl styrene, divinyl benzene, acrylic and methacrylic esters, acrylamide, methacrylamide and acrylonitrile, ionic groups being introduced into polymers thereof by e.g. hydrolysis or sulphonation.  The membrane may be supported on a substrate of a material resistant to strong acid or alkaline solutions, such as a fabric woven from glass fibres or polyethylene or polyvinylidene chloride monofilaments, such supported membranes being preferably prepared by depositing monomer on the substrate and then polymerizing and further treating if necessary.
